'jjThe present improvement in stencil hand stamps or duplicators relates particularly to improvements in the construction of vthe Y inking pad and stencil which are stretched oyer the forami'nous bottom Wall of the hol- 16w; stamp "body" and to the" 1neans :toii detachablymounting the pad and stencil upon the body of'the stamp. Ink padsand stencil sheets are both provided with reinforced op- "p o site ends Inade vby attaching. two-ply -folded reinforcing strips having strengthening steel wlresenclosed 1n the folds of the rein- "forcing strips; suitableperforations or open; 'ing's being cut through the reinforcingstrips 'zjnsti-inside of the tired folded edges, to proide strong holes or openings tofit over suitable lugs or pins carried by the stamp body. The construction of the inking pad and the "stencilis substantially the same with re ard 'toithe reinforcement for" the edges, the-material from which the pad'and' 'stencil are formed being, oficourse, quite difi'erent because of the different requirementsf The hand" stamp -is formed of a hollow body having a segmental cylindrical bottom wen which is perforated throughoutits area excepting atits edges Where the bottom all is attached by soldering or brazing'to the side and end wallsofjthe hollow body. Projecting from oneof thebodyside Walls are the headed pins or studs with which the holes "orpeningsat one edge" of the inking pad and the stencil are engaged, while atthe oppositeside of the 'stamp' body there is 5 provided an adj nstable tension bar consisting "preferably of an anglebari fittlng the' upper corner and side' of thej 'st'ampfbody, said tension bar 1 carryinga plurality of outwardly-presented pins or lugs with which the holes or openings in the opposite edges of the inkingpadand stencilsheet' are engaged. This tension'bar slides upon two orfmore headed pins orfstuds ZPIOjGCt-lllg upWerdly 'from' the top bf lthe 1 stamp body, thebar being perforated to 'fit loosely upon the guide'pins'or studsand pro- I "vided between said guides with some form'ofhand-operatecl=device for raising; the te'nsion r r i h et -mp ody mere y, tret h tension to the pad and stencil which projects over the foraminous body-Wall, 7

These duplicators or stencil stampsare ing over the perforated bottom wall with means for holding the pad and ste'ncilin In the improved stencilhandstamp both the ink pad and the stencil are formed with specially reinforced edges for the engagement of securing means 'upon'the stampbody V the reinforcements being not, only for jected by the adjustable securing means A h v p one edge uponthe' p ns 30 they are'car'efully strength to withstand theusual handling of these parts but in the present case. to stand the stretching tension to which they are subj material such as usually employech to the opreceptionfof thestudsor lugsupon the stamp 'bodypresentlyto be referred to.

When the pad is saturatedwith stencilling ink, it Will be'found 7 stencil put in place and the tension bar again adjusted .for stretching the new stencil. In thischanging of stencils it will be'found that the ink pad remains unchanged in its position because the materialof the pad'is forced more orless into the interstices of the foraminous bottom plate so'that the pad in ef-r V fect interlocks with the bottom plate and does not readily shift in the operation of taking off a stencil and putting a new one on; When it becomes necessary'to renew the inln'ng pad,

' it can, however, be readily taken oif of the supporting pins 30and 38 and a new pad put in its place. The'stencil stamp may be inked by removing the'cover plate 6 and pouring al n d Teft bottom pla e to t print is, to be made,
